and their army in Natal had been weakened, before Buller's final advance, by the departure of commandos going to succour their brethren not only on the Modder, but also in the Cape Colony. The situation on the Tugela was reported to Pretoria almost simultaneously with the news that Cronje was hemmed in at Paardeberg. But owing it may be to the distance which intervened between Kruger and the scene of action, the dour old _voortrekker_ of Colesberg would not hear of any voluntary retirement before the enemy who had driven him out of the Cape Colony sixty years before. He sent an appeal to the Boers of the Tugela which, in an intense human document, displayed his steadfast and touching faith, and which might have been addressed by his prototype Cromwell to the Ironsides. He rebuked the burghers for their cowardice, which he attributed to the waning of their trust in the power of the Almighty to help them in their distress, and with many instances and quotations from Holy Writ, he adjured them to stand fast in faith. He was confident that the cause which he in all sincerity believed to be the cause of the Church of Christ would prevail in the end, and justifiably encouraged by successes in the field against superior numbers he exhorted the commandos to endure without flinching the purification by fire. Kruger's passionate appeal availed, and the waverers returned to their posts. The incident disclosed the power of the factor of moral force, wherein the Boer strength lay; and it will in a great measure account for the prolongation of the war. When their cause seemed hopeless, they comforted themselves with the honest and irradicable belief that its righteousness was the assurance of final success. Though most of their leaders were incompetent, though they themselves were easily discouraged; disobeyed orders; often malingered and mutinied; quitted the field with their wagons which they were reluctant to abandon, under such frivolous pretexts that the _verlafpest_ or leave-plague became a bye-word; though time after time their power of resistance seemed to be exhausted; though in their thousands they were distributed over the British Empire as prisoners of war; though their confident expectation of European intervention was not realized; though they were always greatly outnumbered; they continued stubbornly to defy for the space of two years and seven months the most numerous and the most efficient Army which has ever left the shores of Great Britain, until at last they were worn down by mechanical friction and attrition, and not by the stroke of war. When the Boers were driven out of the Hlangwhane positions, they took up a new position facing S.E. on the left bank of the Tugela. Their right was near the head of Hart's loop, and their centre came within a few hundred yards of the river at Wynne's Hill, whence the line was carried on towards Pieter's Hill.
